i cleaned the maf with an maf cleaner that was labeled on the can, so that was safe, i also checked the maf wires and they were not corroded, rusty, dirty, etc. i have an aem dryair oil-free air filter, and that helped the performance before the problem. i havent check the fuel pressure yet and will do. i noticed that the distributor cap and rotor pins to the wires were corroded with a build up on them. could there be too hot of a spark from the plugs (platnium 2's) ruining the cap and rotor, and contribute to this problem? thanks for your help and info!
